Hello--I used ice as an attempt to reduce swelling of the optic nerve---warmth wouldn't help it, I don't think. Jane
Hello-I'm glad I could help verify your eye problems. My neuro had never heard of it being gray either--or momentary.She doesn't believe a lot I say even after 36 years! It might make you feel better to put ice in a glass an hold it up to your eye. I think it might reuce swelling of the optic nerve, it feels good, and it sure can't hurt. I've done kit for years! Write anytime, Jane
